HARRY T. KINGSBURY, OF KEENE, NEW HAMPSHIRE.

PRINTING-PRESS.

Application fi1e(1 March 25, 1907.

To all whom it may concern:

Be it known that I, HARRY T. KlNGSBURY, a citizen of the United States, residing at Keene, in the county of Cheshire, State of New Hampshire, have invented certain new and useful Improvements in Printing- Presses, of which the following is a description, reference being had to the accompanying drawing, and to the letters and figures of reference marked thereon.

My invention relates to new and useful improvements in printing presses, and particularly to that class of press provided with a platen mounted to rock toward and from a stationary bed over which an oscillating ink roller is moved.

The invention consists in certain improvements in the mechanism for rocking the platen and for simultaneously moving the ink roller.

The invention further consists in the manner of supporting the ink roller.

The invention still further consists in the particular means for supporting the chase on the bed of the press.

The invention still further consists in the improvements and arrangements of the parts hereinafter described.

In the accompanying drawings which show one embodiment of my invention, Figure 1 is a side elevation of a press embodying my improvements, showing the platen in its extreme outer position; Fig. 2 is a view similar to Fig. 1, showing the platen as closed upon the bed of the machine; Fig. 3 is a rear elevation of my improved press; Fig. 4 is a detail view showing the manner of securing the chase to the bed of the press; Fig. 5 is a detail perspective view, showing the manner of supporting the inking roller; and Fig. 6 is a detail view, showing partly in section the means for operating the ink distributing plate.

The bed plate 1 of the press has rising therefrom a supporting frame 2, which carries at its upper end the ink-distributing plate 3. The supporting framework 2 has a bearing 4, in which a journal stud on the lower side of the ink-distributing plate rests and rotates.

The chase 5 is provided with side pieces 6, having curved outer ends 7, which serve as a means to guide the ink roller as it moves across the face of the type carried by the chase. The lower face of the chase is provided with a depending bifurcated lug 8,

which engages a stud 9 carried by the bed of the press, as shown in F ig. 1. The chase is retained against the bed of the press by means of the spring 10, having an opening in its outer end, which engages the lug 11 extending from the upper face of the chase. Then it is desired to remove the chase from the bed of the press, the spring 10 is lifted, and the upper end of the chase released, after whichthe same may be lifted from the supporting stud 9.

The platen 12 is carried by an arm 13, which is pivoted at 14 to the supporting framework of the press. The pivotal point 14 of the arm 13 is substantially in the same vertical plane as the face of the type, so that as the platen engages the type, the same is moving substantially at right angles to the face of the type. Said platen is provided with the usual gages 15, and retaining fingers 16. The retaining fingers 16 are mounted on a cross bar 17, which cross bar is oscillated by means of a swinging finger 18, engaging a depending projection 19, carried by the bed of the press.

As a means for oscillating the platen, I have provided a hand lever 20, which is pivoted at 21 to the framework 2 of the press. Said hand lever has a depending projection 22 to the outer end of which is pivoted a link 23, by means of a pivot bolt 24. The other end of the link 23 is bent upward and pivoted at 25 to the arm 13 of the platen.

It will be noted that as the hand lever is swung about the pivotal support 21, that the link 23 will cause the platen to be rocked about its pivotal support, and be brought into engagement with the type. The inking roller 26 is carried by the swinging arms 27. Each of said arms 27, as shown in Fig. 5, is pivoted to a bracket 28, which is carried by the bed of the press, as clearly shown in Fig. 6. Said bracket is secured to the bed by means of suitable lugs and rivets 29, 29.

The arm 27, as shown in Fig. 5, is bent outward, then upward, and backward upon itself, and is provided with suitable openings 30, to receive the rod 31, which directly supports the inking roller. This rod has its upper end 32, bent at right angles, and engages a bearing socket in the ink roller. The lower end of the rod is provided with a collar 33 (see Fig. 2).

Intermediate the collar 33 and the bent portion of the arm 27 is a spring 34, which normally holds the ink roller in contact with arm and through which the cross bar 37 of y. the brackets 28.

pivoted to the upper end of an arm 4], and

I roller has left the distributing plate, and a a tooth.

Fig. 1, the cross bar 37 is nearest the pivot of moved away from the pivot of the arm 27,

T; slot 44. A portion of the cam slot 44 is said frame, a bed carried by said frame, an

the yoke also extends. As the hand lever is operated the yoke is moved upward from the position shown in Fig. 1 to that shown in Fig. 2 and the cross bar 37 will follow the cam slots 38. This movement of the yoke, through the engagement of its bar 37 with the slots of arms 27, causes the arms 27 to swing about their pivotal connections with It will be noted from the shape of the cam slot 38, that the connection of the cross bar 37 with the arm 27, is moved toward and from the pivotal connection of the arm 27. When the parts are in the position shown in the arm 27, and, therefore, the movement of the inking roller will be very rapid; but as the inking roller leaves the chase and moves onto the distributing plate, the bar 37 has and, consequently, the movement of the inking roller will be very slow.

As a means for turningthe distributing plate, I have provided a pawl .40, which is engages the ratchet teeth 42, formed on the under side of the distributing plate. Said arm 41 is pivoted at 43 to the bracket 28, and has a depending portion formed with a cam curved to correspond to the cam slot 38 in the bracket, while the remaining portion of the slot 44 extends at an angle thereto.

When the inking roller is moving down from the distributing plate, the cross bar 37 which also engages the slot 44, will convey no movement to the arm 41, until after the portion of the slot which coincides with cam slot 38, is passed. At this time, the inking further movement of the cross bar causes the lever 41 to swing, and the ink-distributing plate to be rotated the distance of one ratchet Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is

1. A printing press, comprising a supporting frame, a platen pivotally supported upon inking roller, a swinging arm for carrying said inking roller, a rocker arm pivoted upon said supporting frame, a link for connecting said rocker arm to said platen, a yoke connecting said rocker arm to said swinging arm, and a bracket having a guiding slot for said yoke substantially as described.
